Hi Robert,

Ha, I've almost forgot this submission. How did you dig it out of the
vast archives? ;)

In my memory this example had a problem of not working properly with
FBO. Qt uses a separated QGLFramebufferObject class to do it. I will
soon build the latest Qt distribution to see if this could be solved.
Under Windows, the example is fine with multi-threaded. I'm also going
to have more tests with my Ubuntu tonight.

BTW, this made me recall another osgposter example, which discussed
the implementation of high-res rendering. Is it possible to reopen
that thread someday? :) But I'd like to first have a review myself.

Cheers,

Wang Rui
